Perhaps you should try some spelling variations:
thuat lanh » thuat lap, thuat san
ban hanh » ban hang
pham cuc » pham chuc, pham duc, pham cua
lanh ky » hanh ky, nganh ky, thanh ky
cuc ban » cua ban, cac ban, cuu ban
hieu ve » hieu van
hieu va » lieu va, hieu qua
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
cua tu » cua tuc, cua su, cua cu

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh ky lang xa hoi. ((hieu va) OR (hieu ve)) pham cuc ban hanh vi ((cua te) OR (cua tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh ky lang xa hoi. ((hieu va) or (hieu ve)) pham cuc ban hanh vi ((cua te) OR (cua tu))~".
• Adding a wildcard symbol may retrieve word variants: thuat lanh ky lang xa hoi. ((hieu va) or (hieu ve)) pham cuc ban hanh vi ((cua te) OR (cua tu))*.
